The lead scientist at Percheron Therapeutics discussed the design of the study assessing proteomics of ATL1102.
"We're keen to understand what else the drug was doing. So, we used a proteomics approach... and we looked at 7000 different proteins in the blood. We collected patients’ blood at the end of the study and at various times during the study... So that was the designs, looking at the different protein changes during that period.”
ATL1102 modulated sVCAM-1, LTBP4, BMP5, BMP6, IGF-I, and Thrombospondin-1 closer to control levels (P <.0005), genetic modifiers of disease progression and fibrosis, in non-ambulant boys with Duchenne muscular dystrophy (DMD). ATL1102 is an antisense oligonucleotide and targets inflammation as a secondary cause of muscle damage in patients with DMD.
These data, from a proteomic analysis of plasma from participants in a phase 2 trial (NCT05938023) of ATL1102, were presented at the 2024 Muscular Dystrophy Association (MDA) Clinical and Scientific Conference, held March 3-6, in Orlando, Florida, by George Tachas, PhD, lead scientist, Percheron Therapeutics.
CGTLive® spoke with Tachas to learn more about the study and its design. He discussed how the study is analyzing the proteomics of blood samples collected from the participants at different timepoints throughout the study. He also shared that Percheron will be publishing a paper on the proteomics analysis and the full readout of the generated data, which include surprising findings on CTGF and fibrosis in patients with DMD.

Bendamustine Is an Effective Alternative to Fludarabine-Based Lymphodepletion in LBCL
December 7th 2024In the wake of fludarabine shortages, lemphodepletion with bendamustine was found to be an effective alternative compared for patients with large B-cell lymphoma being treated with a CD19-directed CAR T-cell therapy.
